WILLIAM G. TAYLOR, OF PITTSBURG, PENNSYLVANIA, ASSIGNOR TO THE TAYLOR BURNER AND ELEOTRO-PLATING COMPANY, LIMITED, OF SAME PLACE.

WATER-HEATER AND BURNER THEREFOR.

SPECIFICATION forming part of Letters Patent No. 641,656, dated January 16, 1900.

Application filed July 8,1899. Serial No- 723,230. (No model-) To aZZ whom it may concern.-

Be it known that I, WILLIAM G. TAYLOR, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Water-Heaters and Burners Therefor, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure l is a side elevation, partly broken away, showing my improved water-heater and burner. Fig. 2 is a top plan view of the burner. Fig. 3 is a side elevation of the same, partly in section; and Fig. 4 is a central vertical section, on a larger scale, of a drop-tube attachment of the heater.

My invention relates to water-heaters and the burners used in connection therewith and is designed to improve the action of heaters having drop-tubes and a central circulatingpipe by providing a new arrangement of burners to coact therewith.

In the drawings, 2 represents a pilot-light burner having a stem 3, which extends through the center of a main burner,consistin g of a body portion 4, with branches 5, which extend therefrom, these parts having upper perforations forming a burner which surrounds the centrally-located pilot -light burner. It will be noted that the pilot-light burner is separate and distinct from the main burner, but forms practically a part thereof, and is of sufficient size to materially heat the water in the heater and keep it at a uniform temperature when no water is being drawn from it.

6 is the gas-supply pipe, having a regulating-valve 7 and provided with a right-angled bend containing a valve controlled by a thermostat located in a water-barrel 8. The supply-pipe 9 for the pilot-light burner'leads from between the valve 7 and the thermostatcontrolled valve to the mixer 10 for the pilotlight burner. The main gas-supply pipe 6 leads to the mixer 11 at one end of the main burner.

This heater consists of a cylindrical body or shell 12, having centrally screwed to its lower head a short tube-section 13. To the lower end of this tube section is secured a head 14, which is bolted to a lower head 15, with an intervening diaphragm or partition 16. The partition-is provided with aseries of tubes 17, open at both ends and which extend downwardly into the drop-tubes 18, secured in the lower head. A central circulating-tube 19 opens into the chamber 20, between the diaphragm and the lower head, and extends upwardly within the heater-body. A depending shield 21 is secured to the lower head and surrounds the drop-tubes, which tubes are arranged in annular series, leaving an open cen= tral space which is entered by the flame of the central pilot-light burner. This burner being located immediately below the circulating-tube 19 act-s directly upon the water entering this tube, and when no water is being drawn cit-as, for instance, during the night-it will keep the water at an even tem perature while the main burner is shut oif. The burners are supported by depending wires secured to the shield 21 and engaging screws 22 in the side portions of the main burner.

The hot-watcr-outlet pipe 23 leads from the top of the heater-body, and a branch pipe 24 connects the outlet with a short pipe 25, leading directly into the chamber 20. The outer end of the pipe 25 is provided with a spigot 26, by which hot water may be immediately drawn from the heater.

When in operation, the thermostat controls the flow of gas to the main burner, cutting of the supply of gas when the temperature reaches a certain limit and allowing gas to flow to the main burner when a house spigot is opened and water enters the heater through a supply-pipe 27, leading to the waterbarrel 8, the lower end of which is connected to the heater-body. The gas-supply to the pilot-light being independent of the thermostat will constantly t'urnish gas to the pi1otlight burner, which conveys heat to the water in the central portion of the chamber 20 and which will pass upwardly through the circulating-tube 19.

The advantages of my invention result from the peculiar relation of the pilot-light burner and main burner to the drop-tubes and the circulating-pipe.

central space in the central portion of the head, a central circulating-pipe over the said space, a main burner located beneath the drop-tubes, and a pilot-light burner arranged centrally to direct its flame into the central space of the lower head; substantially as described.

In testimony whereof I have hereunto set my hand.
